CREAM AND BUTTER SEPARATOR.-

Specification of Letters Patent.

Patented Jan. 21, 1908.

Application filed May 16. 1907- Serial No. 374011- To all whom it mayconcern:

Be it known that I, ALPHEUs FAY, a citizen. of the United States,residing at Louisville, in the county of Jefferson and State ofKentucky, have invented certain new and useful Improvements, in Creamand Butter Separators, of which the following is a specification.

The object of my invention is to provide improved means for extractingcream or butter from fresh milk and my invention consists in thecombination and arrangement of parts hereinafter described and claimed.

The drawing is a sectional elevation of a separator embodying myinvention.

On opposite sides of the body A of the separator are secured sockets Badapted to receive stems c on brackets 0. Body A is preferably made ofmetal enameled on the inside. A shaft D is mounted in suitable bearingsc on brackets C and a gear E is pinned or otherwise secured to shaft D.Adjacent to gear E, a shell F is loosely mounted on shaft D and a doublepinion G G is rotatably mounted on a stud g carried by shell F. PinionGr meshes with gear E and pinion Gr meshes with a gear H which is pinnedor otherwise secured to a shell J loosely mounted on shaft D. Shells Fand J face each other as shown to inclose gears E and H and pinions Gand G. Gear teeth f and j are formed on shells F and J to mesh withgears Z and m on the hollow shafts L and M, which bear at their upperends in sockets c on brackets C. Openings 0 are provided in sockets cfor admitting air to the open ends of shafts L and M. The shafts L and Malso have bearings 0 and p in brackets O and P which engage stems c andare secured in position thereon by sets screws 6. Shaft D is providedwith one or more crank handles d for operating the separator. Shafts Land M carry combined air pumps and agitators Q and B so constructed thatwhen rotated they draw air through shafts L andM and introduce it intothe milk or cream in body A. Simple agitators S and T are also carriedby shafts L and M and a draining faucet U is provided for body A.

In operation. upon rotation of shaft D pinions G and G are rotated bygear E, and pinion G meshing with gear H carried by shell J is alsorotated. This rotates shell J under the influence of the action fromgear E. But shell F is also free to rotate, and being connected withpinions G and G will rotate under the influence of the reaction fromgear E. Since the shells F and J are provided with gear teeth meshingwith gears Z and m on shafts L and M, it will be seen that shafts L andM will thus be rotated in the directions indicated one under theinfluence of the action and the other under the influence of thereaction. As the action and reaction are always equal, an equal amountof power will be transmitted to each shaft and an equilibriumestablished between the two shafts. Thus when the resistance on oneshaft becomes greater than that on the other, the corresponding shellwill slow down in speed, but take more power, while the other willincrease in speed, taking less power. This naturally decreases the resistance on the slower shell and increases it on the other shell, sothat the former is permitted to increase in speed while the latter isforced to decrease in speed. Inasmuch as the agitation in body Anecessarily causes different resistances upon the two shafts and shells,their speeds will be constantlyvarying, thus greatly increasing theagitation. In use fresh sweet milk is placed in body A and shaft Drotated to agitate the milk and introduce air therein. .This iscontinued for from about three to five minutes, when the action isstopped and the milk allowed to come to rest, when the cream will riseto the top of the milk. This will ordinarily take from five to tenminutes after the milk has come to rest. Then by opening faucet U theseparated or skimmed milk is .drawn off leaving the cream in body A. Byvary ing the volume of skimmed milk drawn ofl the cream may be obtainedwith any ordinary per cent. of butter fat desired. The faucet is thenclosed and the operation continued upon the cream in body A. This iscontinued until the butter is separated from the cream, which willordinarily take about three to five minutes. The butter may then beremoved and worked in the usual manner. The cream residue may then beremixed with the skimmed milk and good and serviceable fresh sweet milkobtained, which contains all the solids originally in the milk exceptbutter fat.

While I have illustrated and described the preferred means for carryingmy invention into effect, this is capable of variation without departingfrom the spirit of the invention. I therefore do not wish to be limitedto the exact construction set forth, but

What I claim as new and desire to secure by Letters Patent is:

1. In a cream or butter separator, the combination of a separatingchamber; an operative shaft mounted thereon; a shell loosely mounted onthe shaft and carrying Within a pair of eccentrically mounted pinionsconnected together; a driving gear secured to said shaft and meshingwith one of the pairs of gears; a second shell loosely mounted on theshaft and carrying Within a concentrically mounted gear meshing With theother pinion, said shells being mounted to inclose and protect the gearsand pinions; gear teeth on the exterior of the shells; a pair ofagitating shafts in the separating chamber and carrying gears meshingWith the gear teeth on the shells, andagitators on the shafts,substantially as specified.

2. In a cream or butter separator, the 20 combination of chamber A;shaft D mounted thereon; shells F and J loosely mounted on shaft D; gearE on shaft D; gear H on shell J; pinions G and G carried by shell F andmeshing With gears E and H; gear teeth f 25 and j on shells F and Jagitator shafts L and M carrying combined agitators and air pumps Q andR and agitators S and T and gears Z and m meshing With the teeth onshells F and J, substantially as specified. ALPHEUS FAY.
